Help figuring out a regular expression!

I am writing a simple html parser (the HTML is in a one-line text file already on disk). After it reads the file, I'd like it to look for all instances of an anchor tag set which use a specific class (<a class="someClass"...).

So the program will read the file, scan through it for all instances of anchor tags that start like this: <a class="someClass" and print out (to console) the plain text (SomeText1, SomeText2, etc.) found betwen the opening/closing anchor tags.

Would someone be able to figure out the regular expression to do this?
